DRAFT-RIGGING FOR CARS.

SPECIFICATION forming part of Letters Patent No. 693,643, dated February18, 1902.

Application filed May 24, 1901.

To whom it may concern:

Be it known that 1, WILLIAM H.EMERICK, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Draft- Rigging for Cars, of which thefollowing is a specification.

This invention relates to draft-rigging for cars. I

The object of the invention is to provide a construction ofdraft-rigging for cars which is simple and efficient and wherein renewalof the coupling bar or arm in case of breakage may be effected easilyand readily.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in't'ne construction, combination,location, and arrangement of parts, alias will be more fully hereinafterset forth, as shown in the accompanying drawings, and finally pointedout in the appended claims.

Referring to the accompanying drawings, and to-the Various Views andreference-signs appearing thereon, Figure 1 is a top plan View of adraft-rigging constructed in accordance with the principles of myinvention, parts being broken out and in section. Fig. 2 is a horizontallongitudinal section of the same on the line 2 2 of Fig. 3 looking inthe direction of the arrows. Fig. 3 is a view in sideelevation. Fig. 4is a view in vertical longitudinal section on the line 4 4, Fig. 1,looking in the direction of the arrows. Fig. 5 is a transverse sectionon the line 5 5 of Fig. 4 looking in the direction of the arrows. Fig. 6is a view similar to Fig. 1, showing a slightly-modified arrangement ofparts embraced within the spirit and scope of my invention. Fig. 7 is aView in vertical longitudinal section on the line 7 7 of Fig. 6.

In the practical operation of cars the coupler arm or bar by which onecar is attached at its end to the next adjacent car is subjected toheavy usage by reason of the pull exerted thereon when the cars arecoupled up and by reason of the impact thereon during the couplingoperation. By reason of this heavy usage breakage of the coupler arm orbarfrequentlyoccurs. Inpriorconstructions of draft-rigging for carsembodying means of attachment of the coupler-arm to the carfierial No.61,678- (No model.)

body it has been necessary in making repairs or replacements of thecoupler arm or bar to remove the draft-rigging from thesupporting-sills. This consumes time and involves the taking apart andreplacement of the parts of the draft-rigging, which is a practicalobjection the present invention is particularly designed to overcome,andin accordance with the principles of my invention I provide aconstruction of draft-rigging which is exceedingly simple and efficientand wherein the coupling arm or bar may be readily removed and replacedin case of breakage without the necessity of removing, taking apart, orreplacing the draft-rigging.

In the drawings I have shown various constructions and arrangements ofdraft-rigging embodying the principles of my invention.

Referring to Fig. 1, reference-signs 8 and 9 designate the side sillsconstituting the framework upon which the draft-rigging is supported andto which the rigging is connected, said sills being bolted or otherwiseconnected to the car-body in the ordinary manner.

Reference-signs 10 and 11 designate counterpart castings respectivelymounted upon the rigging-sills 8 9. Said castings are provided withflanges 12, arranged to receive the sills 8 9 therebetween to aifordefficient means for clamping or bolting said castings to said sills,said castings being mounted upon the opposed inner faces or sides of thesills 8 9, respectively. On the inner opposed faces of castings 1O 11are formed cooperating guideways 13 14, each adapted to receive a leg 1516 of a U-shaped belt or strap, which constitutes the draft-strap. Theouter ends of the legs 15 16 are slotted to receive therethrough a keyor pin 17. The sills 8 and 9 are also correspondingly slotted inalinement with each other and with the free ends of the legs 15 16, theends of the key or pin 17 extending into the slots 18 19 in said sills,as clearly shown in Fig. 2.

Reference-sign 2O designates the coupler arm or bar, which may be of theusual or ordinary construction and having a transverse slot or openingtherethrough, as shown in Figs. 2 and 4, to receive therethrough the pinor key 17. In this manner the coupler-arm may be detachably connected tothe ends or legs 1516 of the draft yoke or strap. The

ICO

slots 18 19 in the sills 8 9 should be of sufficient size or area toafford clearance for lateral movements of the key 17 under theexigencies of the impact or draft imposed thereon in coupling or inhauling a car. Interposed between the end of coupler-arm 20 and theconnecting web portion 21 of the draftyoke is a suitably-arrangedspring,which may be ofthe ordinary construction and arrangement, such asis usually employed in draftriggings for the purpose of relieving theshock and jar of the pulls or impact imposed upon the coupler arm or barin use.

I have shown in Figs. 1, 2, 3, and 4 a simple arrangement of spring orspring-buffer comprising end plates 22 23, suitably connected togetherby rods 24 25, upon which said plates loosely slide. Upon eachrodismounted the coiled springs 26 27. All the parts of thespring-buffer mentioned constitute a connected frame arranged to bereceived between the castings 1O 11 and held in place by the flanges 28,which flanges, if desired, may be made removable to afford access tosaid springs when desired. The plate 22 of the spring-buffer is arrangedto take bearing against the web or connecting portion 21 of thedraft-yoke, and the plate 23 of the buffer is arranged to take bearingagainst the inner end of the coupler arm or bar, as most clearly shownin Figs. 2 and 4.

From the foregoing description it will be seen that when a pull isexerted upon the coupler-arm the buffer-plate 23 will take bearingagainst the shoulders 30 of the castings 1O 11, which thereby constitutea stop for said bufier-plate, and the pull exerted upon the coupler-arm20 is transmitted through the draft-yoke and is imposed upon thebufferplate 22, which being movable and loosely mounted upon the bolts24 is drawn yieldingly toward the plate 23, thereby imposing acompression upon the springs 26 27. Similarly in case of an endwiseimpact upon the coupler-arm-as when two cars come together, forinst-aneethe buffer-plate 22 strikes against the shoulder 31 (seeFig. 1) of the castings 1O 11, and the endwise projection of coupler-arm2O forces the buffer-plate 23 toward plate 22 and imposes a compressivetension upon the springs. In this manner the parts are relieved of shockor jar. If'desired, the ends of the key or pin 17 may be retained inplace and said pin or key prevented from working out of place by meansof keepers 32 33.

From the foregoing description it will be seen that in case of breakageof the coupler arm or bar the same may be removed and replaced withoutdisturbing the other parts of the draft-rigging by merely removing thekeeper or the keepers 32 33 and withdrawing the locking key or pin 17,and when the new coupler arm or bar is inserted the same may be quicklylocked or secured to the draft-rigging by again inserting the lockingpin or key'17 in place through the openings 18 19 in the sills 8 9 andthe openings in the ends of the legs 15 16 of the draft-yoke and througha transverse opening in the coupling-arm.

The construction shown in Figs. 6 and 7 differs from that abovedescribed with reference to Figs. 1, 2, 3, 4, and 5 only in thearrangement of the buifer-springs. For instance, the construction andarrangement shown in Figs. 1 to 5 and above described is known in theart as a twin arrangement, and the construction shown in Figs. 6 and 7is known in the art as the tandem arrangement, of springsthat is, in theone case the set of springs are arranged side by side, whereasin theconstruction shown in Figs. 6 and 7 said springs 40 41 and 42 43 arearranged one behind and in line with the other, each set of.

springs being held between relatively movable buffer-plates 44 45 46 47.In the construction shown in Figs. 6 and 7, however, two locking pins orkeys 48 49 are employed, the pin 49' passing transversely through thesills 5O 51 and the ends 52 53 of the couplingyoke and also through thecoupler-arm 20, and the other passing transversely through slots oropenings in the sills 5O 51 and betweenthe two sets of buffer-springs,said key 48 forming a stop or shoulder for buffer-plate 46, and the rearconnecting-web of the yoke-strap forming a bearing for the correspondingplate 44 of the other set of springs to effect a compression of thesprings under the influence of a pull exerted upon the coupler-arm,.andsaid key 48 forming an abutment for plate 45 of the one set of springs,while the end of the coupling-arm 20 forms an abutment for thecorresponding plate 47 of the other set of buffer-springs to effect thecompression of said springs under the influence of animpact imposedlongitudinally upon the coupler-arm. In other respects the constructionin the two cases may be the same.

It is obvious that my invention is not to be limited or restricted toany particular construction or arrangement of buffer-springs, and otherforms of buffer-springs may be employed in connection with my inventionwithout departure from the spirit or scope thereof. It is also obviousthat changes and variations in the details of construction andarrangement of parts would suggest themselves to persons skilled in theart and still fall within the spirit and scope of my invention. I do'not desire, therefore, to be limited or restricted to the exact detailsshown and described; but,

Having now set forth the object and nature of my invention andconstructions embodying the principles thereof, what I claim as new anduseful, and desire to secure by Letters Patent, is

l. A draft rigging for cars comprising side sills, independentcounterpart castings mounted upon the opposed sides or faces of saidsills, said castings provided with shoulders and having cooperatinglongitudinallyextending seats or ways in the opposed faces thereof,follower-plates arranged to be rea draftyoke loosely seated between saidcastings and arranged to straddle said plates, a coupler-arm and aremovable key for connect.-
